Ever wanted to use something like example.com/backend or example.com/dash to access your WordPress dashboard or login area? Here is a simple snippet of PHP for your functionality plugin or functions.php to do just that — it uses standard WordPress URL rewrite API.

Update: turns out that in WordPress 3.4 there are new default redirects (/admin, /dashboard and /login) implemented in the core (see this ticket). So here is a better way to add your own redirects which will work only if you don’t have a page or post with the same name (slug) already:

Istivan, thanks for mentioning the default “login” one — I didn’t know about it!

The answer to you second question is yes — this filter leaves all of the default rewrites intact. Secondly, you can’t remove wp-admin, because it is an actual folder that is part of the WordPress core file structure.

This is great Kaspars! I have a question: Do you know how to change the registration module so new subscribers pay a small fee to be able to subscribe to my site without interfering with my e-commerce plugin?
What I’m saying is something you can change/add in the wordpress framework without touching the current e-commerce-paypal standard already installed in the system.
This is because as soon as I enable “anyone can register” on my settings, I get a lot of new subscribers with fake emails.
I’d rather not install another plugin to do this, I prefer just add a little code snippet, if it’s possible.
Thanks for your advice!
